Largest synthetic gene ever built offers insights into anti-malarial drug resistance

have developed unique patterns of mutations in the three genes mentioned above. Now, researchers can tell where a drug resistant parasite comes from depending on the varied mutations in the three different resistance genes, Roepe said. "There are pat...
Largest ever study of genetics of common diseases published today
... most significant new findings are four chromosome regions
containing genes that can predispose to type 1 diabetes and three new genes for Crohn's disease (a type of inflammatory bowel disease). For the first time, the researchers have found a gene linking these two autoimmune diseases, known as PTPN2. The...
